How to enable remote Connection sql server 2008

27 de Março de 2012 – 10:48

Error message:

“A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server)”

How to solve this issue?

There are a couple of things that might be going on here… (All of the following configurations are made on the computer running your SQL Server 2008 instance)

Allow remote connections to this server

The first thing you want to check is if Remote Connections are enabled on your SQL Server database. In SQL Server 2008 you do this by opening SQL Server 2008 Management Studio, connect to the server go to Properties -> Connections -> Check “Allow remote connections to this server”.

Problem with Identity Specification in SQL…

23 de Março de 2012 – 12:17

Error message when changing the identity column to “Yes” and save the changes:

“Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can’t be re-created or enabled the option Prevent saving changes that require the table to be re-created.”

It’s not a bug. It’s a safety measure added to SQL 2008’s management studio to indicate that the change that you’ve requested to the table requires that the table be dropped and recreated.

It’s there so that people don’t ‘accidentally’ make changes in production that will take hours.

use “SET IDENTITY_INSERT” command, for more info, see SQL BOL.

Or turn off the warning under tools–>options–>designers–>table and database designers

uncheck prevent saving changes that require table re-creation

SQL Server Dumper

23 de Março de 2012 – 10:51

SQL Server Dumper enables you to dump selected SQL Server database tables into SQL INSERT statements, that are saved as local .sql files and contain all the data required to create a duplicate table, or to be used for backup purposes. You can choose to create an individual .sql file for each table, or combine all selected tables into a single file.

This program implements the following special features:

  • Foreign Keys> order tables in text file in order to insert data without colisions/errors
  • Primary Key IDENTITY> guarantees the value of the IDENTITY field
  • Reference to itself> eliminates the constraint and at the end create it again

SQL SERVER – Insert Data From One Table to Another Table

8 de Março de 2012 – 10:20

INSERT INTO SELECT – SELECT INTO TABLE

Following three questions are many time asked on this blog.

How to insert data from one table to another table efficiently?
How to insert data from one table using where condition to anther table?
How can I stop using cursor to move data from one table to another table?

There are two different ways to implement inserting data from one table to another table. I strongly suggest to use either of the method over cursor. Performance of following two methods is far superior over cursor. I prefer to use Method 1 always as I works in all the case.

Insert Multiple Rows in SQL Server

6 de Dezembro de 2010 – 14:02

In SQL Server 2005, in order to insert 3 rows to a table, you had to run 3 INSERT statements:

insert into Customers (Name, City, Phone) values (‘Customer #1’, ‘Jerusalem’, ‘2343245’)

insert into Customers (Name, City, Phone) values (‘Customer #2’, ‘Tel Aviv’, ‘0987345’)

insert into Customers (Name, City, Phone) values (‘Customer #3’, ‘Haifa’, ‘275466’)

In SQL Server 2008, you can insert multiple rows in a single insert statement that takes a number of value arrays:

insert into Customers (Name, City, Phone)

values

(‘Customer #1’, ‘Jerusalem’, ‘2343245’),

(‘Customer #2’, ‘Tel Aviv’, ‘0987345’),

(‘Customer #3’, ‘Haifa’, ‘275466’)

A WMI error has occurred and no additional error information is available

26 de Maio de 2010 – 16:04

This can happen when you have different versions installed. For example, if you install SQL Server 2005 SP3 and later, and only then install the Reporting Services.

In this situation it should be rerun after the SP3 installation of Reporting Services
